We switched to #2 when it seemed like Ty was getting frustrated with getting the milk out of the nipple. I don't remember how old he was though. I tried out the #2 and he seemed happier. You could always try it and see how it goes. We only used the #3s for bottles with a little cereal added when he was a little older.
